  • Patent number: 4060037
    Abstract: A pallet having a rectangular shaped load carrying deck of generally uniform thickness. The deck is formed of several sheets of flexible wooden material with spring characteristics. The sheets of flexible wooden material are superimposed on one another and formed to be arcuate about a single axis. The sheets are glued together so as to constitute an arcuate structure substantially free from inherent tension forces in its unloaded condition and having sufficient elasticity to assume a substantially planar form under load. Supporting means are attached to the under convex side of the deck. The supporting means are arranged in a plurality of parallel rows extending in the direction of the single axis. One of the rows is located in the plane intersecting the axis and a line on the deck substantially corresponding to the central deck line. A second row of supports extend along the first outer edge portion of the deck and a third row of supports extend along a second outer edge portion of the deck.
